Answer:
Technician B
Explanation:
The brakes can lockup due to the following reasons
1) Overheating break systems
2) Use of wrong brake fluid
3) Broken or damaged drum brake backing plates, rotors, or calipers
4) A defective ABS part, or a defective parking mechanism or proportioning valve
5) Brake wheel cylinders, worn off
6) Misaligned power brake booster component
Answer:
a)250.4 °C
Explanation:
Temperature at which pressure of water become equal to the surrounding pressure is called boiling temperature .
The boiling temperature of water at 4 MPa is 250.4 °C.As we know that when pressure of water increases then the boiling point of water also increases.The boiling point of water at 1 ar is 100 °C.So the boiling point of substance is not constant it varies with environment .
Answer:
None of these
Explanation:
There are different types of amplifiers, and each has different characteristics.
- Voltage amplifier needs high input and low output resistance.
- Current amplifier needs Low Input and High Output resistance.
- Trans-conductance amplifier Low Input and High Output resistance.
- Trans-Resistance amplifier requires High Input and Low output resistance.
Therefore, the correct answer is "None of these "
Answer:
ΔU =195 KJ
W=0 KJ
Explanation:
Given that
Mass of air m=3 kg
heat absorb by air =195 KJ
Cv=0.741 KJ/kgK
If we assume that air is as ideal gas so
Given that container is rigid it means that volume of system is constant so W=0
From first law of thermodynamics
Q=ΔU + W
⇒Q= ΔU (W=0)
So ΔU =195 KJ
And work done will be zero because because it is a constant volume process.
B
Now this is a guess sorry but i am positive on this guess
